Found in syslog after adding pam_lastlog module to pam.d: PAM unable to dlopen(/lib/security/pam_lastlog.so) PAM [dlerror: /lib/security/pam_lastlog.so: undefined symbol: logwtmp] PAM adding faulty module: /lib/security/pam_lastlog.so As it seems to be, pam_lastlog depends on libutil.so (where logwtmp leaves), but not linked with it. It's trivial to add -lutil to link command of pam_lastlog, but for now, with new autoconf stuff, this should be in configure.in (as not all platforms have -lutil and/or logwtmp in it, and some (?) ever does not have logwtmp), so I'm not shure how to correct this Right Way... And this is a more general question than just about this pam_lastlog issue. This was/is on all pam releases since 0.71!.. Does anyone uses pam_lastlog at all? :) Regards, Michael.
